NTE1919

Integrated Circuit

Negative 3 Terminal Voltage Regulator,

–15V, 1.5A

Description:

The NTE1919 is a 3 terminal fixed n egative v oltage r egulator i n a TO3 type package designed for use
in applications r equiring a w ell regulated positive o utput v oltage. Outstanding f eatures i nclude f ull power
usage up to 1.5A of load current, internal current limiting, thermal shutdown, and safe area protection
on the chip, providing protection of the series pass Darlington, under most operating conditions.
Hermetically sealed steel packages are utilized for high reliability and low thermal resistance. A low–
noise temperature stable band–gap reference is the key design factor insuring excellent temperature
regulation of the N TE1919. This coupled to a very l ow o utput i mpedance i nsures s uperior l oad r egula­tion.

Note 2. Low duty cycle pulse testing with Kelvin connections required. Die temperature changes

must be accounted for separatly.
Note 3. BW = 10Hz to 100kHz.
Note 4. Ripple attenuation is specified for a 1Vrms, 120Hz, input ripple. Ripple attenuation is mini-

mum of 60dB at 5V output and is 1dB less for each volt increase in the output voltage.
